We present a special bonus episode, sent to us by Christopher Beswick, of a full-length interview he conducted with Gordon Kaye in 1991, when he had returned to work following his life-threatening accident.

This episode marks the end of Season One, and we celebrate with a surprise guest and a “guess the mystery voice” game. Although this episode is called the Jet-Propelled Mother-in-Law, no one can decide what the episode is actually about – as we encounter the people from the café treading grapes, and various other antics around Nouvion – as well as von Smallhausen savouring his rare moments of revenge.

The podders attempt to keep track of the sausages. After the first twenty they give up, exhausted. Kim entertains with a tale of pranks on tour. Christian Dyall gets a bit of worship for his imaginative and lavish costumes. But where is the real painting of the Fallen Madonna with the Big Boobies? Did the writers even know?

As Mimi takes to the skies as an airborne nun, it is an astounding week for cast impressions. Guy treats us to a Bertorelli, as well as a Michelle of the Resistance, and Kim delivers a terrifyingly realistic von Smallhasuen. A double disguise for Herr Flick – first as a gypsy playing the fiddle with gloves on – then into Helga's uniform to fool no one as Frau Kinkenrotten. Kim entertains with a tale of trying to fly a box kite with her dad.

This week, despite distractions from Alexa, a photographer called Rowan and a bottle of Prosecco, Kim, Guy and Richard maintain their usual level of sober professionalism while discussing the episode in which the new characters of Captain Bertorelli and Mimi la Bonq are introduced.

Is there such a thing as an episode-numbering nerd? Or geek? Or both? Question: Who literally cares which season or blinkin' episode this is? Answer: Kim, as well as some of the show's most militant archivists. Anyway, this is Pod 24, and the fun starts long before we unveil our literally special guest. Tune in and meet her/him/them. The series says farewell to Sam Kelly as Hans, as he is catapulted over the wire, and Francesca Gonshaw as Maria, who is posted to Switzerland in a parcel. For a change, iced tea is served in Kim's kitchen.

The committee starts to get strict about overuse of the word "wonderful" – which is likely to have little effect. More fun and frolics in the prison camp, and the trio celebrate the rare privilege of seeing Richard Marner do the Can Can, Gruber dressed as a nun, and Helga singing a long-overdue Lili Marlene.

Amid panto reminiscences from our pod trio (tripod), we discover that Fanny's pet name for her lover van Gogh was Bobby. While Guy and Richard get all knowing about the McGuffin device in detective stories, Kim insists it is a burger chain meal deal. They discuss the lengths that some performers will go to in order to secure a close-up, including gaining access to the camera scripts (some of them dummies created by the production team to throw them off the scent). Meanwhile, Kim, Guy and Richard protest too much at the suggestion they would ever chase a close-up.
